XMLTextWriter To WiterData Using C#.Net Application

We have thousand of Data To Write In XML File & To Write Data We use XmlTextWriter.

We can across one problem while Writing XML File,

Error Is While Writing Attribute : Invalid high surrogate character (0xDC50). A high surrogate character must have a value from range (0xD800 - 0xDBFF).

As A Error Solution : We decided to Replace Problematic Data With Space..

But XMLTextWriter Wan't Allow To Write Anything After WriterState is In Error. (it Says : Token StartAttribute in state Error would result in an invalid XML document.)

Here is sample Code To Relicate Error:

XmlTextWriter writer = new XmlTextWriter("C:\employees.xml", Encoding.UTF8); writer.WriteStartDocument(); writer.WriteStartElement("Employees");

           try
            {
                string data = "뿿�� ";
                writer.WriteAttributeString("Company", data);
            }
            catch (Exception ex)
            {
              //Here I Got Error For surrogate character                     
                writer.WriteAttributeString("Company", "");//Trying To Write Again

Is there any way To write Attribute value ones it get in State Of Error?

Thanks.

Check your data string before adding it to the writer or use a CDATA block using : http://msdn.microsoft.com/en-us/library/system.xml.xmltextwriter.writecdata.aspx
